XXIII. On some Fresh-Water Entomostraca from the Island 
of Mull, Aryyllshire, collected by the late Mr George 
Brook. By Tuomas Scort, F.LS., Naturalist to the 
Fishery Board for Scotland. 
(Read 17th January 1894.) 
During the year 1890 the late Mr George Brook visited a 
number of small fresh-water lochs in the island of Mull, 
when several gatherings of invertebrates—chiefly Ento- 
mostraca—were collected and preserved. I happened to 
meet Mr Brook on one or two occasions afterwards, when he 
_ spoke of the collections he had made, and offered to hand 
them over to me for examination if I would arrange to send 
for them. Having at the time a good deal of other work on 
hand, I delayed doing so till there was some prospect of my 
being able to examine and describe them. Owing to the 
lamented death of Mr Brook last year, I had given up all 
thought of the collections, but a few months ago Mr Binnie 
—Mr Brook’s assistant—informed me that they were still 
intact, and that I could have them; and this explains how I 
have been able to prepare the fellduane report. 
The collections having been carefully worked up, the 
report I now propose to lay before the Royal Physical 
Society contains a record of the results obtained. I have 
the more confidence in submitting this communication,
